Outer Protective Hoses

For selecting an outer protective hose suitable to your project, special requirements concerning flexibility, mechanical stability and watertightness are very important and have to be considered.

Approximate outer diameter values of heating hoses with polyamide protective braid, using the example of heating hoses series H 12. If other outer protective hoses or a different heating hose series is used, the outer diameter might increase by up to 10 mm.
